Synchronous Step-Down DC/DC Converter has high current density.

Press Release Summary:

Offering selectable 6, 8, and 10 A current limit thresholds, SWIFT™ 10 A TPS54020 comes in thermally enhanced, 15-lead, 3.5 x 3.5 mm HotRod™ QFN package that protects integrated 8 mΩ high-side and 6 mΩ low-side MOSFETs from parasitic inductance. MOSFETs provide up to 96% efficiency from 12–1 V, and standard features include frequency synchronization, 180° out-of-phase switching, and 200 KHz to 1.2 MHz adjustable switching frequency.

Original Press Release:

TI Introduces 10-A SWIFT(TM) DC/DC Converter with Highest Current Density

17-V synchronous buck converter integrates MOSFETs and features tiny HotRod(TM) package

DALLAS -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced a new synchronous step-down DC/DC converter with integrated MOSFETs in a very small 3.5-mm by 3.5-mm HotRod(TM) QFN package. The SWIFT(TM) 10-A TPS54020 features the highest power density and includes frequency synchronization, 180-degree out-of-phase switching and selectable current limit to power FPGAs, system-on-chip (SoC), DSPs and processors in high-voltage, space-constrained communication, gaming and industrial computing applications. Using the converter together with TI's WEBENCH(®) online design tool simplifies high-voltage DC/DC conversion and speeds the design process. For more information and samples, visit

The new HotRod integrated circuit package protects the integrated MOSFETs from parasitic inductance and allows low resistance, enabling high current and efficiency and small size. The thermally enhanced, 15-lead package is 50 percent smaller than similar offerings.

The TPS54020 joins TI's point-of-load DC/DC converter family, which includes the 6-A TPS54623 in a 3-mm by 3-mm QFN package, and the 12-A LM21212-1 and 15-A LM21215 converters, offered in a thermally enhanced eTSSOP-20 exposed pad package.

Key features and benefits of the TPS54020 DC/DC converter

--  Integrated 8-milliohm high-side and 6-milliohm low-side MOSFETs provide up to 96-percent efficiency from 12 V to 1 V.

--  Selectable 6-A, 8-A and 10-A current limit thresholds allow optimization for efficiency at a lower output current, while reducing the size of external components.

--  180-degree out-of-phase switching reduces input current ripple by up to 50 percent.

--  200-KHz to 1.2-MHz adjustable switching frequency supports small output inductors and capacitors for further space savings.

Availability, packaging and pricing

The TPS54020 DC/DC converter is available in volume now from TI and its authorized distributors. It is offered in a 15-lead HotRod QFN( )package and is priced at US$3.45 in 1,000-unit quantities.
